Mark Reed Crispin, inventor of IMAP, passed away on Friday, December 28, 2012 at Martha and Mary Healthcare Services in Poulsbo Washington. He was born on July 19, 1956 in Camden New Jersey and was 56 years of age.
Very few people have (almost single handledly) designed protocols and implemented (free) software that has facilitated communication among millions of people. Mark was one of them and thanks to his monumental achievement of IMAP (and the fact that the Net cannot “forget” his posts on comp.mail.imap) he will always be remembered and always there to teach those who want to hear him.
As someone who has had the privilege to exchange personal emails with him, I am deeply saddened by his departure. I think he is the first of my email heroes that leaves.
